Split from this thread.
I have been unable to access msgs on my app for weeks now.
No matter how many times I reset the app, cold boot the xbox, keep things turned off, keep things turning on, etc, etc, etc, Whenever I start up the app on windows 10, I get the 'Try again - we had trouble getting your conversations.' Of course, no indication of what the trouble was, what the problem was, nahhh.. Just the "hey, our software isn't working now - too bad."
Xbox msgs work just fine. App and the Beta app don't work.
After weeks of this, I'm getting extremely annoyed. It's messages, not rocket science...
